As huge quantity of water continued to reach Jurala and Srisailam reservoirs from the upstream projects in the Krishna basin, the authorities of Srisailam dam had to open up its spillway gates further twice on Tuesday to allow discharge of higher volume of flood.
After lifting four crest gates at 2.45 pm and two more gates at 7 pm to 10 feet height each to discharge over 1.67 lakh cuses flood from the spillway on Monday, the authorities had to raise the height of the gates further to 17 ft in the wee hours of Tuesday to increase the discharge to over 2.51 lakh cusecs.
However, as the quantity of inflows into the reservoir were approaching about 4 lakh cusecs on Tuesday morning, the authorities lifted the gates further up to 23 feet height around 9 am to take the discharge of flood to nearly 3.2 lakh cusecs from the spillway itself. In addition, another 72,000 cusecs of water was also being let into the river course after power generation in the power houses of Telangana and Andhra Pradesh at the joint project.
As the inflows into Almatti have fallen below 2 lakh cusecs, the authorities there have started building water level in the dam by reducing the discharge of flood downstream constantly. Accordingly, the outflows from Narayanpur towards Jurala were reduced to about 63,000 cusecs by 6 pm on Tuesday from about 2.09 lakh cusecs at 6 am.
However, the discharge of flood from Jurala to Srisailam continued to remain high even on Tuesday night (9 pm) as the inflows were to the tune of 2.65 lakh cusecs and the discharge of flood through the spillway and power house was 2.48 lakh cusecs.
The discharge of flood from Tungabhadra too was reduced to about 72,000 cusecs from nearly 1 lakh cusecs. Inflows into Srisailam were in the measure of 3.31 lakh cusecs at 9 pm.
Supplementation of flood to Jurala from Bhima, from Ujjani and a few other dams, was continuing in the range of 50,000 cusecs. Meanwhile, a Central Water Commission (CWC) bulletin stated that the Krishna at Arjunwad in Satara district and Kurundwad in Kolhapur district in Maharashtra was still rising and flowing in the above normal flood situation with the trend of further rise.
